... Also, I was amused by John Hickenlooper. I mean that genuinely and kindly. He participated in the night’s most entertaining exchange, when he mocked Sanders’s grand plans by saying that they won’t come to pass just because Sanders wishes for them or throws his arms up in the air. Sanders does wave his arms a lot, or, rather, flaps them, so much so that you wonder at times if he’s trying to make a point or take flight. Anyway, Hickenlooper imitated him. Then Sanders imitated Hickenlooper. Then Hickenlooper imitated Sanders again. And for a few seconds, they looked like participants not in a presidential debate but in a calisthenics class.
